Sound difference on pipe sizes...

    Possibly a dumb question...which pipes are louder> Rhinhart's 3 1/4" or the 4"?

    Just curious, would think larger is louder, but smaller could be based on the same outflow being forced through a smaller opening.

    Really don't know the answer but to me, if the baffle design was identical, a larger exit pipe would produce a lower frequency exhaust tone/note than a smaller exit pipe would. Since our ears perceive lower frequencies to be lower in db or sound pressure, I would say the 3.5" would appear louder but only in db. (maybe ?)

    Now that is based on identical baffles which I am sure they are not.

    Good question.. I am sure others will chime in.

    As Hoople has said, the factor that matters more so is the baffle size and not the pipe size. Typically the larger diameter of the baffle the louder the sound.
